[Pharo-project] Bug: don´t found #convertToCurrentVersion:refStream:

When a object is serialized, a Morph for example , and the class of that morph change, when i try deserialize the morph i get the error does´nt not understand #convertToCurrentVersion:refStream: I did see older images of Pharo and exists that method, defined in Object and Morph too. Seems than adapt the old class form to new version, if changed. The caller of that message is the class SmartRefStream. My image is a Pharo BETA 10418.
